Job description

Overview

Here at Nexi Digital Finland we care for our people, and we believe our People First mindset keeps us at the forefront of technology and makes us the best place to work. Our way of working drives bold ideas and innovations, supported by robust R&D. With a strong product portfolio and a commitment to staying one step ahead, we continuously evolve to meet the dynamic market needs.

Do you want to protect the critical day-to-day infrastructure of digital society? Then you might enjoy working with us.

We are looking for a hands-on Software Architect (Cloud Backend) to join Nexi Digital Finland!

Our AWS-based payment platform has powered Nordic transactions for years with a focus on security and high availability. We’re now scaling out and rolling out new features to prepare for a broader European expansion. Join us to shape the next phase of a platform built to keep payments flowing reliably across Europe.

Role Overview

This is a senior developer role with architectural responsibilities. You will:

• Write, deploy, and maintain production-grade backend code
• Shape the architecture of distributed systems that prioritize consistency, resilience, and low-latency processing
• Solve for reliability and scalability in a real-world, high-integrity transaction environment
• Participate in operating and improving our system in production
• Collaborate closely with teammates to make pragmatic, forward-looking decisions
• Work closely with stakeholders across product, infrastructure, and operations

About the Team

• We build and operate the backend that routes payment transactions — a critical link between terminals and the wider payment infrastructure. We take its reliability and security seriously, because when it fails, payments don’t go through. That responsibility shapes how we work: as a small, experienced team focused on reliability, simplicity, and real-world impact.
• We operate with a high degree of autonomy—empowering you to take ownership, experiment, and grow your expertise over time. The payment domain is complex and nuanced, offering numerous opportunities to expand your technical and domain knowledge as you progress. We maintain a steady pace and protect time for deep, focused work.
• We support a healthy work-life balance and trust people to manage their time responsibly.
• This role is based in Espoo, Finland, and follows a hybrid model. Candidates should be located within commuting distance of the office.

What You Bring

We’re looking for someone curious, proactive, and comfortable taking initiative. You enjoy working with others, sharing knowledge, and taking ownership of your work, and you\'ll find a team that values the same.

Our stack includes: TypeScript, Rust, Python, AWS (with a focus on serverless), MySQL, DynamoDB, Containers, Linux.

You don’t need to know everything already — we value strong fundamentals, a willingness to learn, and the ability to adapt quickly. Many of us have picked up parts of the stack along the way, and we’ll support you in doing the same.

What’s in it for You?

• Attractive salary and a competitive benefits package to reward your expertise and contributions
• Tech equipment: Get the tools you need to succeed, including the latest technology to support your work
• Join an international team: Collaborate with experts from across Europe and bring your ideas to life in a dynamic, global environment
• Grow and develop: Gain hands-on experience and structured training through our PayTech University, designed to accelerate your career and help you reach your full potential
